Question

the recipe for a cake calls for the following dry ingredients 1/3 cup of sugar 3/4 cup of cornmeal and 1/2 cup of flour what is the total number of cups of dry ingredients called for

Answer 1

1 7/12 cups

Explanation:

change all denominators to 12. Then, you can add like terms.

1/3 x4 to numerator and denominator =4/12

3/4 x3 to numerator and denominator =9/12

1/2 x6 to numerator and denominator=6/12

total, you get 19/12. Since it is an irregular form, turn into a mixed number. 12 can go into 19 once. 7 left over, keep the denominator of 12.

Answer 2

Answer: 19/12 cups

Explanation:

1/3 + 3/4 + 1/2 =

4/12 + 9/12 + 6/12 = ==> 12 is the LCM of 3, 4, and 2

(4+9+6)/12=19/12 cups
